Last Saturday night, 'Stereoscope' by Blinkenlights delighted thousands of onlookers as Toronto’s City Hall became the world’s largest interactive computer screen.

The installation will continue to run every night until Sunday, October 12 at 7 a.m.

'Stereoscope' is an interactive light installation built by German group Project Blinkenlights that transforms the landmark towers into a huge display screen by arranging and controlling lamps behind each of the 960 windows of the building.
